Babbling

 Listening to 11 30 for 30 Freestyle by Drake, he throws in a couple of words in Spanish.  Just like he did on the track, Odio featuring Romeo Santos.  Usually it's kind of funny when you hear somebody speak Spanish when they normally don't.  But in music, it doesn't sound funny.  When an artist spits out Spanish words randomly on their track, when they normally do not, it gives it a twist-a little bit of an drawing you in feel. Listening to it on their track they sound so confident with how they rap the words, so it sounds good, great even.  Even though the artist thinks they sound weird, the confidence helps cancel that weirdness out.  Confidence=Art.
